Walker a worry for Blades chief

Walker, 19, was taken off early in the second half at the Walkers Stadium and replaced at right-back by Derek Geary, who will start if Walker fails to make it.Kevin Blackwell, without Lee Williamson (hamstring) and Darius Henderson (gluteal muscle) until the end of January, is unlikely to make many, if any, other changes.Andy Taylor is expected to continue at left-back following Toni Kallio's recall by Fulham, while striker Henri Camara will be hoping to force his way back into the starting line-up after scoring his second goal for the Blades on Boxing Day.
